Programmatically change title of Custom Action Bar

Question

I am neither able to programmatically change the title of custom action bar nor able to add profile image to action bar. I failed to understand where my implementation is wrong. Below is my code:

actionbar_home

<RelativeLayout
    android:layout_width="match_parent"

    android:layout_height="wrap_content"

    android:background="@color/tabbackground"
    android:layout_marginLeft="5dp"
    android:layout_marginRight="5dp"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">
    <ImageView
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/profileImageActionBar"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerVertical="true"
        android:visibility="visible"
        app:border_width="1dp"
        app:border_color="#FFFFFF"
        android:layout_alignParentLeft="true"

      />


    <TextView
        android:id="@+id/actionbar_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:gravity="center"
        android:maxLines="1"
        android:singleLine="true"
        android:text="Home"
        android:textColor="@color/white"
        android:textSize="22sp"/>
</RelativeLayout>

        }

Answer 1

In your case, you are inflating the view twice.

In this line:

 View mCustomView = mInflater.inflate(R.layout.actionbar_home, null);

And this line:

getSupportActionBar().setCustomView(R.layout.actionbar_home);

So, when access the "actionbarTitle" you are referencing the first inflation, not the actual view attached to the ActionBar (as the method setCustomView(int id) inflates the view itself, see docs).

In order to access the actual title you either need to use:

getSupportActionBar().setCustomView(mCustomView);

Or initialise the "mCustomView" view, after you set the resourse to the ActionBar:

getSupportActionBar().setCustomView(R.layout.actionbar_home);
mCustomView = getSupportActionBar().getCustomView();
